KeyMods are like a life-hack for your keys, adapting your key in a *click* to work with any Ferris cover. Insert your key at an angle between the tabs, then rotate and push till it clicks. Your key is now Ferris-ready. In your pocket, your bag or dropped on the ground–they'll stay snapped together. The patent-pending MagLock nesting magnets let your securely snapped keys rotate freely. Sold in sets of 2 with different colored edges, use these guys to build yourself a tidy color-coded key system.
